The Nautilus 11, often referred to as the Nautilus 11M, represents a rare and specialized chapter in Canadian boat building. Produced by Aztec Yachts in Niagara-on-the-Lake, Ontario, during the 1980s, this 36-foot monohull was the brainchild of naval architect Henri Adriaanse. With only a handful of units—estimated at approximately five—ever reaching completion, the vessel was never a mass-market product. Instead, it was positioned as a semi-custom, "blue water" cruiser intended for sailors who prioritized structural integrity and offshore capability over the lightweight agility of contemporary production racers. The hull is characterized by a robust fiberglass layup, a hallmark of the Aztec yard, which sought to compete with the heavy-duty reputations of builders like Gozzard or C&C’s more conservative cruiser lines.
